List of gravitationally rounded objects of the Solar System

It contains almost 99.9% of all the mass in the Solar System. By the IAU's definition, there are eight planets in the Solar System; four terrestrial planets (Mercury, Venus, Earth and Mars) and four giant planets, which can be divided further into two gas giants (Jupiter and Saturn) and two ice giants (Uranus and Neptune).

Of the objects that orbit the Sun directly, the largest are the eight planets, with the remainder being smaller objects, the dwarf planets and small Solar System bodies.

This is a list of gravitationally rounded objects of the Solar System, which are objects that have a rounded, ellipsoidal shape due to their own gravity (current or past hydrostatic equilibrium). The 2006 International Astronomical Union (IAU) defines a planet as a body in orbit around the Sun that was large enough to have achieved hydrostatic equilibrium and to have "cleared the neighbourhood around its orbit".

There are a dozen or so confirmed such objects (apart from the Sun), sometimes called planemos, in the Solar System, with others possible.

This list does not include most small Solar System bodies, but it does include a sample of possible planetary-mass objects whose shape has yet to be accurately determined.

Except for the largest, which are in hydrostatic equilibrium, natural satellites (moons) differ from small Solar System bodies not in size, but in their orbits.

Titan is the sixth gravitationally rounded moon from Saturn.

Their sizes range from former dwarf planets and moons to the planets and the Sun.

The Sun's orbital characteristics are listed in relation to the Galactic Center, while all other objects are listed in order of their distance from the Sun.
